Their excuse? And then your list? wow.
Ok, why should Bungie pander to the checkbox clan? IF the game is 720p with some form of AA this clan will then proceed to move goalposts to the next preconceived checkbox from what single item they percieve is important. They will continue to gloss over the fact that these games are outputting much more than what was possible last generation or current generation systems posing as advancements from the last. Meanwhile, Bungie and outfits like Infinity Ward laugh all the way to the bank with their refined COMPLETE PACKAGE while these gadflys pull out all the vitriol they can muster to satisfy a vocal minority and/or the run-of-the-mill fboy.
Yes, let's cut the game down to far less enemies than Halo 3, use uninteresting gears of war flocking AI on everything, make it a single player affair, and toss in Natal for good measure. And now let's run at 1080p. Do you see the flaw in resolution bulletpoints for anything above SD 480 with total disregard for the COMPLETE PACKAGE? "But game/system X does/doesn't yadda yadda... this means game/system Y is garbage/awesome, 1.5/next-gen, blah blah blah" ALL ignoring the forest for the trees.
I do no expect Reach to be a masterpiece in any way, shape or form nor do I expect it to be some disasterous affair seeking bulletpoints rather than what's good for the GAME. I expect it to have the formula that worked on all previous games INCLUDING graphics/sound/Live/etc with bells and whistles the 360 can produce that I definitely couldn't get last gen or perhaps even on current gen systems.
